--- Uxn core unroller script
---
--- This script updates src/uxn-fast.c when Uxn's opcode set changes, so that
--- updates in the human-readable src/uxn.c core can be easily converted into
--- high-performance code.
---
--- To run, you need Lua or LuaJIT, and just run etc/mkuxn-fast.lua from the top
--- directory of Uxn's git repository:
---
---     lua etc/mkuxn-fast.lua
---
--- This file is written in MoonScript, which is a language that compiles to
--- Lua, the same way as e.g. CoffeeScript compiles to JavaScript. Since
--- installing MoonScript has more dependencies than Lua, the compiled
--- etc/mkuxn-fast.lua is kept in Uxn's repository and will be kept updated as
--- this file changes.
